LOCOMOTIVE-BOILER FRONT-END HINGE.

vApplication led September 25, 1920. Serial No. 412,648.

To all whom 'it may concerns;

Be it known that I, HARRY VrssnRrNG, a citizen of the United States, and a resident of Kenilworth, Cook County, State of Illinois, have invented certain new and useful Improvements in Locomotive-Boiler Front- End Hinges, of which the following is a specication.

This invention relates toi closure supports and particularly to a support for the type of closure used in the boiler of locomotives and commonly termed' the front end as it is the plate for closing the forward end of the boiler.

Although this invention is illustrated and described in connection with the closure for the front end of a locomotive boiler, it is to be understood that the invention is capable of use in other relationships and with other types of construction.

This plate is large and extremely heavy and according` to approved railway practice is secured to the boiler front by a great number of stud bolts and nuts circumferentially arranged adjacent the outer edge of the front plate. In order to make the joint between the boiler front and the front end plate absolutely tight, the nuts are turned down as closely as possible. When it is desired to remove the front end plate to reach the inside of the boiler, the nuts are removed and the front plate moved away from the boiler shell. This removal of the front plate is extremely difficult, as'the front plate will stick to the studbolts and to the boiler front, a natural result of the rusting effect and of the exposure of the parts to the elements. In replacing the front plate on the boiler, similar diiiiculties will 'be encountered particularly if any irregularities should have developed in the relative positioning of the stud bolts.

Still another difiiculty encountered in the removal of this front plate is that its weight is such that a crane and tackle are found necessary to carry the weight of the plate as soon as it is moved away from the position in which it isA supported by the boil- -This necessitates that the engine be moved to a spot where such crane and tackle are at hand.

The principal objects of` Athis invention, therefore, are to provide an arrangement whereby the front end plate can be moved away from the boiler front without the eX- penditure of time and effort hitherto found necessary; the provision of means for moving the front plate away from the boiler front by the application of force directly against the inside surface of the front plate and `at a point within the confines of the' plate; the provision of an improved arrangement for causing said plate to properly seat itself on the boiler front, when it is desired to replace the plate end in closing position; the provision of an improved structure in which the front plate can be moved to a position away from the boiler without at the same time moving the front plate from a position of support by the boiler; `the provision of a novel mechanism which will permit the front plate to be moved outwardly away from the boiler front and out of direct contact therewith and which will then ermit` the front plate to be moved to the site so as to permit free access to the boiler interior while still retaining the front plate at all times in a position of support by the boiler; the provision of means for positioning this mechanism most advantageously from the standpoint of structure design and also so as to place `the mechanism in a protected position and hidden from view; together with further and additional objects as will hereinafter appear.

In attainingthe stated objects and certain additional benefits and advantages, I have provided a construction` wherein Figure 1 shows a front view (partly broken away) of the boiler front with the end closure plate attached in operative position;

Figure 2 l shows a section through the mechanism for supporting the end closure plate from theboiler shell, and

Figure 3 shows a section taken at a right angle to that of Figure 2.

Looking' iirst at Figure 1, it will be noted that the boiler, 10,` shown is circular in cross section and that the end or closure plate, 11, for the front end of the boiler is secured to the boiler front by means of the circular row of stud bolts, 19., carried by the circular ring, 13, secured to the boiler, and 'passing through the corresponding opening on the front end plate, 11. Upon these stud bolts are threaded the nuts 14.

Supported from the inside wall of the boiler, 10, by means of the flanges 15, 16 and 17 is the main supporting bracket, 18, of substantial. dimensions, which as shown is bex-like in construction. Slidably mounted within and supported by the bracket, 18, is the member, 19, which carries the frontend closure plate 11. The member', 19, is guided so as to have a sliding movement baclr and forth on the bracket support, 1S, parallel to the longitudinal axis ot the boiler. lt is obvious, therefore, that as this member, 19, is reciproeated the closure plate, 11, will be vmoved with it eitheiI aivay from or towards` its closure position on the boiler front. l have thus provided an arrangement tor supporting the closure plate from the inside ot the boiler Wall which is not only substantial in character, but which also permits oit the front end plate being moved aivay trom the boiler opening Without moving the end plate from its position ot' support by the boiler shell.

` For imparting to the member. 19, the aforementioned reciruocation, the threaded member, 20, is mounted treely ilor rotation in the supporting flanges. 15 and 21, said member, Q0, being held against any bodily movement longitudinally by the abutment members, Q2, iixedly carried by the member, 20, on each side oil' the flange, 15.

rlhrez'uiledly engaging the screw,u 20, is the nut, :23, hele against. rota-tion with the screiv. E20, by depending part. 2l, thereof engaging` the sliding member, 19, between the side vralls and the end flanges 25 and 2o.

Ey this arrangement, When the screw 20 is rotated, the nut, 23, ivill be caused to travel thereon either baCkiva-rdly or torwardly. depending upon the direction in which the screvv is rotated. The nut,` Will carry vvith it the sliding member, 10, and will thus cause the end closure member, 11, to move either to or from its closing position.

The screw, E20, is provided with the squared end, 9.7, to receive a crank-handle by which the screw. Q0, can be manually rotated, and to admit this the trent plate, 11, is provided With an opening through which the cra-nk can be inserted, which opening is normally closed by the plug, 9.8. Tlllh'en it is desired to rotate the screw, 20, the plug, 28, is removed and the crank is inserted through the opening` into enga-gement with the squared end 27.

lt will thus be seen that l have provided a support for the front end closure plate, and mechanism tor positively moving said support and end plate both baclnvardly and tor- Wardly, all located Within the boiler interior, protected trom blow and hidden -from view.

Furthermore, by the use ot the rotating screw the force manually used in rotating the crank is applied most advantageously to move the closing plate 11.

Mounted upon the sliding member, 19, is the hinge pin, 29, upon which is pivotally ifi-eine? mounted the hinge members, 30, integral With the member 31 rigidly secured to the end plate, 11. Upon viewing Figure 2, it will be' noticed that the hinge tor the end closure plate, 11, is located at a substantial distance inwardly from the edge, 3Q, ot the plate, 11. lllhen, therefore, the sliding member, 19, is moved outwardly a distance sutilci'ent to permit the outer edge, 32, to clear the boiler at the time the end plate, 11, is turned about the hinge pin, 29, the end plate can be swung to one side. This procedure is assisted considerably by the tact that the hinge pin, 29, is placed inwardly off the outer edge oit the plate 11.

To limit the extent to which` the end closure plate, 11, can be sivung'to the side, the slide, 19, is provided With the flange, 33, which acts as an abutment stop tor the end closure member, 11, as clearly shown in dotted lines in Figure 2 ot the drawings.

l have thus provided a structure in which the mechanism by which the closure member is mounted tor bodily movement and 'for pivotal movement is hidden trom vie Y and is given a substantial support trom jdie inside ot the boiler. I have Afurthermore provided structure in which both parts ot the hinge are movable together as a unit with the end closure element. I have further provided a construction in which the mechanism used not only moves the end closure plate, 11, to unseat it but also moves it in the opposite direction to torce it on its seat and one in which the force is applied to the end plate in a straight line trom a point inwardly et the plate.

Having thus described my invention and illustrated its use, what l claim as new and desire to secure by Letters Patent is- 1. ln combination, a boiler having an, opening thereto, a closure for said opening, and means tor supporting said closure trom said boiler, said means being movable to and trom a position Within the boiler.
